Reset to let the engine learn current condition quicker is simply by removing the battery negative terminal for a few minutes (5 at least) and then reconnecting it.

DON'T do this just before an inspection that includes an emissions check, since the computer will read out 'not ready" and you'll have to go back later (takes some drive cycles to complete all it's self checks).
